Here at Seti, there is a requirement for the default applications GPU that the AMD GPU has CAL support, even for OpenCL usage. Your GPU does not have CAL support, AMD didn't add it. Doesn't matter which drivers you install, your card will only show up as OpenCL capable.

And with that you cannot get work from the server. Not with the default applications. So in that case, you'll have to use third party applications, such as the Lunatics applications, which use the anonymous platform and when newer versions are released in the future, rely on you to update them then. See https://setiathome.berkeley.edu/forum_thread.php?id=71867 for more information and the link to the thread with a lot of reading to do.Jord

To be specific, AMD's Computer Abstraction Layer (or CAL) was a software development before there was OpenCL (not to be confused with OpenGL). From Wikipedia:

Another important part of the SDK, the Compute Abstraction Layer (CAL), is a software development layer aimed for low-level access, through the CTM hardware interface, to the GPU architecture for performance tuning software written in various high-level programming languages.

In August 2011, AMD released version 2.5 of the ATI APP Software Development Kit, which includes support for OpenCL 1.1, a parallel computing language developed by the Khronos Group. The concept of compute shaders, officially called DirectCompute, in Microsoft's next generation API called DirectX 11 is already included in graphics drivers with DirectX 11 support.

With the release of OpenCL 1.1 and Microsoft's DirectX 11 both supporting all the features needed for GPGPU computing, AMD has deprecated CAL in it's software, and many CAL functions will not work on AMD HD7000 series and later graphics cards.

Your AMD A10-6800K APU is a Richland core with an integrated AMD HD8000 series graphics chip, which means that most CAL functions will not work correctly on it either.

The only work-around is to either wait for the project to release an updated application that doesn't require CAL (the current stock application was written by a volunteer, so it could happen, though I have no idea when), or you can use a third-party application such as the Lunatics apps as Ageless suggested which do not require CAL but still work with SETI@home.
